GDI+ Roatating image Button

[monoscout999]

I finish a script that demonstrates how to click a moving GDI+ image, still don´t understand it at 100% but i think that is a start, comments will be apreciated.

EDIT You can adjust the rotation speed by draging over the shape.

I was trying to play with some color algorythm to calculate how to change the color while the object is rotating and simulate a white light from the top of the GUI.. i have failed, but this random effect come up

I have some errors with autoit 3.3.3.1 (GDIP.au3 not found !)

Do you have a solution please ?

Download from the link in my signature... is an extension of the GDIPlus library.

I am glad to see that others are playing with GDI+, too.

Nice work!
